<P>PROBLEM TO BE SOLVED: To provide a refractory mortar cured material in which cracks are suppressed, and whose thermal shock resistance is excellent. <P>SOLUTION: Disclosed is a refractory mortar cured material formed by applying refractory mortar obtained by kneading ceramic particles with an inorganic binder having a silanol group together with water on the surface of a ceramic base material. The average particle size of ceramic particles in the refractory mortar is 10 to 50 μm, the difference of 90% particle size and 10% particle size is 10 μm or more to 60 μm or less, the average pore size of the refractory mortar cured material is 5 to 25 μm, and the width of pore size distribution is 20 to 80 μm, so that the cracks may be suppressed. More preferably, the bulk density is 0.9 to 1.5 g/cm<SP>3</SP>. <P>COPYRIGHT: (C)2009,JPO&INPIT |
